This workbook includes five state and transport properties of air and seven of water. All of them are functions of temperature. Users may invoke these user-defined (extrinsic) functions exactly as are the supplied functions (sine, cosine, sum, etc.). They allow the design engineer to do multiple calculations readily without cumbersome table lookups. These functions were developed for use in the Sweaty Runner and Lister Bag projects. A discussion of the former project assignment may be found in: Ribando, R.J. and Galbis-Reig, V., “Convective Heat and Mass Transfer from a Runner Using Some Modern Spreadsheet Features,” Computers in Education Journal, Vol. VIII, No. 4, Oct. – Dec. 1998, pp. 22-28.
As with all items in the HTT software collection, we urge the user to verify the accuracy of these property functions before using them. The NIST Chemistry WebBook is an excellent resource for doing so.
